No house is 7 years old this February, new construction, I built it.
Dianne, I don't think so, I live alone, and I doubt anyone would have replaced bulb without my knowledge , ceilings are 12ft high so its not easy to change any of the lights. Also I live somewhat remote
so not a lot of guest.
Still puzzeled by it, I doubt it is ghost related, but I thought I would share it anyway.
